"Brother, settle the account, the deal I mentioned is: whether it is now or in the future, you will give me a set of various types of armor."

Silent!

Tony is silent, Pepper is silent, and Yang Xin is also waiting in silence......

"What can you give?" For a long time, Tony Stark slowly spat out these words.

"Alchemy!" Yang Xin said solemnly.

"Alchemy? Medieval magic? In fact, I don't think that alchemy exists in this world, and even if it does, it's just another science. Tony Stark said he didn't believe Yang Xin's words.

"Alchemy is not magic, although magic does exist in this world, of course, your understanding is not wrong, but what I mean by alchemy is a law, the law of equivalent exchange.

By alchemy, I understand the inner laws of matter: understanding, decomposing, and reconstructing, alchemy must be carried out according to the law of "equivalent exchange": in order to obtain something, it needs to be exchanged for the same price, and if the price is not enough, any part of oneself (part of the body, memory, etc.) needs to be filled and taken away as a price.

And in the kind of alchemy I am talking about, there is one of the biggest taboos - the refining of the human body. No matter how rich your knowledge is, how thorough your theory is, and how high your wisdom is, you must never refine the human body!

In this way, it is difficult for you to feel what alchemy is in words, but you can feel it yourself, and alchemy is not so much alchemy as a science. ”

After that, Yang Xin stretched out his index finger and put a little on Tony's eyebrows, and the treasure brushed out of the treasure system: alchemy, was taught to Tony Stark.

This kind of alchemy, from "Fullmetal Alchemist", this kind of alchemy, which is very different from the magic side, is very suitable for Tony Stark, Yang Xin is not worried that Tony Stark will not trade with him, let alone worry that Tony will be repaid, because, Tony Stark has his own pride.

His pride does not allow him to do things that are unaccountable, otherwise, he would not stand at the pinnacle of mankind and do things that are "mortal in body and comparable to gods".

At this time, Tony Stark was closing his eyes and experiencing the alchemy brought by Yang Xin, and this experience came to night, and after a long time, Tony Stark opened his eyes, and then commanded the intelligent robotic arm to "crackle" and transport a large number of materials.

Tony Stark then began to draw an alchemical diagram on the ground, and eventually, Tony Stark drew a large circle around the periphery of the alchemical diagram, connecting all the nodes together.

With both hands together, slam on the top slap!

A flash of golden light flashed, and the pile of materials that the mechanical arm had brought was gone, replaced by a red suitcase.

Yang Xin knew that this was the Mark V and the suitcase armor.

Tonik Tucker stepped forward, quickly put on his armor, and then looked at his steel suit in a daze, and it took a long time to come to his senses.

"This is alchemy? Understanding, decomposing, reconstructing, equivalence? …… Is this really science? It's not scientific at all! ”

"Strictly speaking, this is a law, a law that embodies knowledge, and this law is inseparable from knowledge and wisdom."

"Tony, you deserve it!" Yang Xin patted Tony Stark on the shoulder. At the same time, Tony Stark's skills are randomly selected successfully, and the skills are extracted: man-machine integration, Tony Stark's skills to operate mechas.

Yang Xin was thoughtful, and this skill was also very useful. Don't think that you can drive it if you are given a suit of armor, even ordinary cars have to go to driving school to learn and get a driver's license before they can hit the road, let alone such an advanced Iron Man armor.

Tony Stark, who came back to his senses, immediately sent Mark Type 2, Type 3, Type 4, and Type 5 armor and packed them to Yang Xin.

"Do you need me to send someone to send these armors to S.H.I.E.L.D." Out of kindness, Tony Stark said, and at the same time, he also thought with the greatest malice in his heart, if he really wants to send it to S.H.I.E.L.D., I am afraid that he will be immediately detained by the black skin braised egg, which is not only black skin, but also black heart.

"No, I'll take it myself." Yang Xin said, and Shi Shiran took out the four-dimensional pocket.

"Haha, you wouldn't take this little pocket with such a big armor, would you?" Tony Stark laughed, but then, Tony Stark couldn't laugh anymore, his mouth opened like a toad.

I saw that these sets of armor were sucked into the four-dimensional pocket from big to small.

"What is this?" Tony Stark looked up and down at the four-dimensional pocket in Yang Xin's hand like Erha who only saw bones.

"Have you watched the Japanese cartoon "Doraemon"?" Yang Xin suddenly asked.

"What's that? Haven't heard of it. After Tony Stark finished speaking, he also used artificial intelligence to search for cartoons of the Wa Kingdom, but found nothing.

Yang Xin is clear, this is the difference between different worlds.

"It's just an earless tanuki, don't worry about the details, it's a four-dimensional pocket with almost infinite space."

"Can you let the research be studied?" Tony Stark's eyes were like two hernia headlights.

"This is not something that science can explain." Yang Xin shook the four-dimensional pocket in his hand and put it away.

"Okay, I'm just asking, my current research focus is on the development of new energy sources." Tony Stark raised his glass.

Yang Xin knew that this was Tony Stark's relic, and he couldn't wait to study his father's relics, so he was going to send them off.

"Tony, I still want to make a deal with you."

"Oh?" Tony Stark furrowed an eyebrow.

"Didn't the Stark Group close the weapons research and development department, although the weapons research and development department was closed, but your Stark Group must still have a large number of weapons in stock, I want those Jackory missiles in your inventory." Yang Xin said.

The Stark Group must have developed a lot of weapons, and Yang Xin is interested in the Jericho missile, which is simple to operate and powerful, and is an excellent means of attack in the medium and long range.

"Do you want it, or does S.H.I.E.L.D. want it?"

"I want it!" Yang Xin pointed to himself.

"Brother, settle accounts, this is what you said, what do you trade with me, don't mention money, I am not bad for anything else, but not bad for money~" Tony Stark's eyes lit up instantly, he wanted to see what Yang Xin traded with him.

"A metal."

"A metal? What kind of metal on earth does Stark Group not have? Even vibranium. ”

"It's true that the metal Stark Group on Earth has it, but what if it's extraterrestrial?" Yang Xin said, taking out a palm-sized piece of metal from the fourth dimension pocket, which was obtained from the Destroyer, although Yang Xin got a calf from the Destroyer, but trading with Tony Stark, a small piece was enough.

"I'm sure S.H.I.E.L.D.'s protective wall can't stop you, you can hack into S.H.I.E.L.D.'s intranet and see what happened half a day ago?" Yang Xin said.

Tony was half-gone, and moments later, images of everyone fighting the Destroyer appeared in front of Tony's eyes.

"This is called the Destroyer, the ultimate armor of the Asgardian god king Odin, this is an extremely rare divine metal in the universe, although the divinity in it was withdrawn by Odin with the hammer of Thor, the god of thunder, but this is still a rare metal that is rare in the universe."

"Asgard, God-King Odin, Thor? Are you sure you're not telling a mythological story? Tony Stark was shocked.
